Dear Sir,

Can someone explain me, how to calculate the positive-sequence and the zero-sequence impedance of cables.

This infromation I require for short-circuit calculation

Dear Mr..

for MV / HV cable Z0=~ 3Z1 and for LV Z=~ Z1.

But exact calculation also be done.

For better result please contact to cable manufacturer.

Thanks
